Question 1. In 2018, the 6th Kenyan Census recorded the following events:
Total population: 20,399, 000
Urban population: 28% of the total population
Total females: 11,400,000
Males 15-49 years: 4,695,000
Female 15-49 years: 4,750,000
Emigrants: 6,800
Net migration: -1,580
Annual number of births: 580,000
Annual number of deaths: 230,000
Deaths before reaching five years: 38,000
Deaths during the first month: 13,500
Deaths during the first year (<365 days): 24,000
Calculate: a) Population growth rate b) General fertility rate; c) Natural increase rate d) Crude death Rate e) Post-neonatal mortality rate; f) sex ratio of the total population;
a) Population growth rate:
Population growth rate = ((Births - Deaths) / Total population) x 100
Population growth rate = ((580,000 - 230,000) / 20,399,000) x 100
Population growth rate = (350,000 / 20,399,000) x 100
Population growth rate = 0.0171 x 100
Population growth rate = 1.71%
b) General fertility rate:
General fertility rate = (Number of live births / Total females aged 15-49) x 1,000
General fertility rate = (580,000 / (11,400,000 + 4,750,000)) x 1,000
General fertility rate = (580,000 / 16,150,000) x 1,000
General fertility rate = 0.0359 x 1,000
General fertility rate = 35.9 per 1,000 women aged 15-49
c) Natural increase rate:
Natural increase rate = (Births - Deaths) / Total population
Natural increase rate = (580,000 - 230,000) / 20,399,000
Natural increase rate = 350,000 / 20,399,000
Natural increase rate = 0.0171
d) Crude death rate:
Crude death rate = (Number of deaths / Total population) x 1,000
Crude death rate = (230,000 / 20,399,000) x 1,000
Crude death rate = 0.0113 x 1,000
Crude death rate = 11.3 per 1,000 population
e) Post-neonatal mortality rate:
Post-neonatal mortality rate = (Deaths during the first year / Number of live births) x 1,000
Post-neonatal mortality rate = (24,000 / 580,000) x 1,000
Post-neonatal mortality rate = 0.0414 x 1,000
Post-neonatal mortality rate = 41.4 per 1,000 live births
f) Sex ratio of the total population:
Sex ratio = (Number of males / Number of females) x 100
Sex ratio = (9,699,000 / 11,400,000) x 100
Sex ratio = 0.85 x 100
Sex ratio = 85
Therefore,
a) Population growth rate = 1.71%
b) General fertility rate = 35.9 per 1,000 women aged 15-49
c) Natural increase rate = 0.0171
d) Crude death rate = 11.3 per 1,000 population
e) Post-neonatal mortality rate = 41.4 per 1,000 live births
f) Sex ratio of the total population = 85
